STOPPING ATTACHMENT FOR WATCHES.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed. November 12, 1915. Serial No. 61,067.

To all whom it may concern:

Be it known that I, EDWARD T. LEWIS, a citizen of the United States, and a resident of Oceanpark, in the county of Los Angeles and State of California, have invented a new and Improved Stopping Attachment for Watches, of which the following is a full, clear, and exact description.

The invention relates to stopping attachments for watches such as shown and described in the application for Letters Patent of the United States, No. 11088, filed by me on July 21, 1915.

A1 object of the invention is to provide a new and improved stopping attachment for watches such as are loaned by watch repairers to customers, the arrangement being such that the loaned watch, even if wound up regularly by the customer, automatically stops after, say, a week, two weeks or other length of time predetermined by the watch repairer, to induce the customer to return the loaned watch within a reason able time or to pay for the repairs on his own watch. Another object is to permit of applying the stopping attachment to any make of watch without clisorganizing the parts of the watch movement.

In order to accomplish the desired result, use is made of means for automatically engaging one of the train of wheels of the watch movement after the lapse of a predetermined time.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the views.

Figure 1 is a face view of a watch provided with the stopping attachment, portions of the bezel and the dial being shown broken out;

Fig. 2 is a similar view of the same with the bezel and dial removed;

Fig. 3 is a similar view of the same with the parts in a different position;

Fig. 4 is an edge view of the attachment as applied to the watch movement; and

Fig. 5 is a perspective view of a portion of the dial showing the indicating recess.

As illustrated in Figs. 1 and 2, the hour wheel 10 of a watch movement of the usual construction is provided with a pin 11 adapted to mesh with the teeth of a mutilated index wheel 12 mounted to turn on a pivot 13 attached to the front plate 1 1 of the watch frame. The under side of the index wheel 12 is provided with a pin 15 adapted to engage the beveled end 16 of a lever 17 fulcrunied at 18 on the front plate 14, and the said lever 17 is provided at its other end with a pin 19, adapted to engage the teeth of the fourth wheel 20 of the train of wheels of the watch movement to stop the latter, as hereinafter more fully explained. The lever 17 is pressed by a spring 21 held on the plate 14 to normally hold the pin 19 out of engagement with the fourth wheel 20. The free end 16 of the lever 17 normally rests against the peripheral face of the hub 22 of the index wheel to limit the swinging movement of the lever and to aid. a friction washer under the index wheel 12 to prevent accidental turning of the latter. The mutilated index wheel 12 is provided with twenty-two teeth and two teeth are cut out to provide a space 32, and alternate teeth are provided at their faces with numerals arranged in consecutive order from 1 to 10. The alternate tooth next to the tooth marked 10 is provided with an X mark, and the two teeth next following the one marked 1 bear zero marks, as plainly indicated in Figs. 2 and 8. The peripheral edge of the index wheel 12 projects into a cut-out portion 23 in the watch case 21, and over this cut-out portion lies a correspondingly shaped plate 25 projecting from the edge of the dial 26. The plate 25 is provided with a cut-out portion 27 to display one of the index numerals, the X mark or the zero marks whenever the index wheel 12 is turned correspondingly. The plate 25, its cut-out portion 27 and the tooth of the index wheel 12 appearing in the cut-out portion 27 at the time are hidden by the bezel 28 so that the customer can not see any part of the stopping attachment. When the watch is running, the pin 11 engages one of the teeth of the index wheel 12 every twelve hours and consequently the index wheel 12 is intermittently turned twice each day, and during the time the pin 11 engages the tooth marked 6 and the next following tooth the pin 15 engages the beveled end of the lever 16 to impart a swinging movement thereto, and when the mutilated portion 32 is in register with the pin 11 the latter can travel uninterruptedly without affecting the attachment.

The index mark X on the index wheel 12 is so arranged relatively to the cutout portion 32 that when the said mark X ap: pears in the recess 27 then the cut-nut portion 32 is in the path of the pin 11 and consequently the watch can run indefinitely when properly wound up. lVhen either of the index marks 0 appears in the recess 27 then the watch is prevented from running as the pin 19 now engages the fourth wheel 20 with the tooth marked 6 now standing in the path of the pin 11. When the watchis to be loaned to a customer the repairer temporarily removes the bezel 28 unbeknown to the customer, sets the index wheel 12 so that one of the index numerals from 1 to 10 appears in the recess 27, and then the repairer replaces the bezel. hen the watch is now wound up regularly and is running then the pin 11 turns the in dex wheel 12 a corresponding number of days, that is, at the last day the pin 11 moves into engagement with thetooth of the index wheel 12 marked 6 and turns the index wheel so that the 15 now imparts a swinging movement to the lever 17 ,to eng th Pi i th fourth W eel 20, thus stopping the movement. Thus if the repairer desired the return of the watch say in seven days he turns the index wheel 12 until the numeral 7 of this index Wheel 12 appears in the recess 27 It will be no: ticed that the watch when properly wound up by the customer will run seven days and on the seventh day the pin 11 engagesthe tooth marked .6 and turns the index wheel 12 so that the lever 17 is actuated as previously explained to stop the watch movement by the pin 19 engaging the fourth wheel 20.

In practice, the hour hand 29 of the watch extends over the pin 11 so that the watch repairer when setting the watch for any given length of time can readily turn the hour wheel 10 in such position that its pin 11 is out of mesh with the index wheel 12 to allow convenient turning of the same until the desired position is reached.

In order to accommodate the numeral 5 on the index wheel 12 at the cut-out por-v tion 32 use is made of a half tooth for the numeral 5., but this half tooth is not in the path of the pin 11.

It is understood that when it is-desired to have the watch run for an indefinite time or to be sold as a regular timepiece, the watchek m l t rn h inde wheel 12 an the tooth marked X registers with the recess 27. It is further understood that an index wheel with a more or less number of teeth may be used for difierent periods of time at which the watch is to stop automatically even-it wound up to its fullest extent.

In order to set the index wheel the watch repairer need only remove the bezel holding the crystal to obtain access to the index wheel at the cut-.out portion 32 for turning the index wheel to the desired position. After the index wheel is set the {hands may be set either way without disarranging the automatic stop. In my previous application above referred to it is necessary that wheels with a more or less number of teeth are .used for different periods of time at which the watch is to' stop automatically while in my present invention use is made of a single index wheel which can be set for a given period of time.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
